It may help to make yourself a chart or spreadsheet to record your findings while doing voltage tests of hot, cold, and cranking. Not just when you have a no-start. Volts at batt terminal, back-probing terminal of battery cable, starter cable terminal, back-probe starter cable terminal. drop from batt term to starter term . drop from terminal to back-probe of terminal. especially since the prime components have been changed. The common thread is a voltage drop or interrupt in the cabling. And since electrons are hard to watch, and it does lead to difficult troubleshooting, especially when intermittent, charting results may help.
Also, when a no-start occurs, check connections, shake harnesses and track results, you may have a wire somewhere with an internal fault that is masking itself.

Current Volvos:
1998 V70 T5, 112k sat 5 years, still in mechanical coma (finally at the top of the pile )
2004 XC90 T6 AWD: 186k, 60 on transaxle ( traded in )
1998 POS70 N/A: DD/training aid, 236k but really about 240k, I think...ABS module( passed on to son who sold it)

Ironically, I was just browsing on another forum and found this, http://volvospeed.com/vs_forum/topic/21 ... -no-start/ LOL Happy belated Birthday Erik!
We all just want to see you get this solved, and I'm salty because "Sally" won't let me go out and play with mine this week!

No....you will need a simple digital multimeter to perform a voltage drop test on both....positive and negative side.
More than 0.2v of voltage drop per side and you need a new cable.

I want to thank everyone for there help including: Jaydiesel, jreed, erikv11, abscate
The issue was the positive battery cable which was first mentioned. I was very hesitant to change it out since my current independent volvo mechanic kept telling me the cable is not hard and they tested both ends. My volvo guy who retired from the dealership mentioned it has to be the cable as well.
The other day I decided to see if jumping the car got it to work and miraculously it did. I played around with starting the car while the cables were attached and when they were not and came to the conclusion it had to be either the cable or the battery. Since the battery was new, I had my mechanic just change out the cable for my own piece of mind and so far so good.
Appreciate it and Merry Christmas =)
